ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

As an undergraduate I studied physics at the University of Athens. I entered the university in 1955 after successfully passing a national exam (came up fourth in a field of about 700 candidates). Upon graduation and finishing my mandatory two-year military service, the plan was to teach physics either in a public high school or as a tutor for a private for-profit institution, preparing high school students for the national exam.

Palladium finely dispersed in a substrate of kieselguhr (diatomaceous earth) has been successfully used for tritium storage, separation and pumping for a number of years at the Savannah River Site (SRS). Recently SRS has designed and built a new Pd/kieselguhr flow through bed (FTB) prototype for separating tritium from other gases and simultaneously storing the tritium on palladium. The FTB prototype uses single-pass liquid nitrogen for cooling during tritium absorption/loading/storage and electrical heaters for desorption/unloading of tritium. Fourteen (14) hydrogen absorption/desorption or loading/unloading cycles have been conducted with the new FTB prototype. Test results show that all design performance objectives have been successfully achieved: recover >95% of hydrogen gas from feed gas, <5% hydrogen in discharge gas, and >99.9% hydrogen in the desorbed product gas. This paper will discuss the design and operation of the FTB, and results of performance tests such as separation efficiency, hydrogen/tritium storage capacity and temperature profiles during prep cooling, hydrogen loading and unloading.
